The main; objects' of: this inventionv are First; to provide; a covered container; or box' formed'` of` anintegral-blaek whichmay-be quickly and.` easily erected, and: closed and! one which, when closed, is: secure` and! rigid andi at the: same:

time.` one: in which. the cover: may` be*` quickly and easily opened: and reclosed.

Second, to provide. a. container having; these. adyantages; which may be: formed:` of. relatively light paper board'or container stock: and. aty the Same time, is,J quite;- rigid when erected and eiectiyely'protected; eveni when the container is subjected to considerable handling;

Objects0 relating to details; and. economiesV ot the invention; willi appear from the: descriptionr to follow;` The invention is` d'eneds and pointed; out in the claims;N

A preferred: embodiment or the: invention is illustrated, in; the accompanying drawing; in which:

I have: illustrated my invention asembodiedin an elongated container andl for convenience-in descriptiornin the specification and claims, I use t The. embodiment ofA my invention illustrated is formed ofA a: singlet` blank' illustrated? in Fig; 'e and comprises a bottom I?, front wall? 2; rear Wall Schingedly` connected'to-the bottom byfhing ingl scorerY lines conventionally' illustrated; at 4i and; 5;, The; end Walls ISS-5i are hingedly connected to the bottom by the score lines 'I!. The coverr: is hingedly connected to the upper edge of the rean Wall- 3, by the score' line 9:.

The cover is provided with a closure ilap. ill hingedly` connected thereto atY it. The.Y closure flap is provided with locking tongues L2, having locking lugs` I3' projecting from, their outer side edges. The tongues i2 are spaced-longitudinally of, the closure flap |0- for purposes which! will lie. pointedl out as the description proceeds; '1lb-.e front wallj 21 and rearf wall 3: are;` provided! with corner. flaps I4 hingedly connectedi thereto atl i5.

cover: closed andx one whicha the: contents ate Y Y 25 adaptedtoireceive the tonguesV i2'.

The, end. walls 6 have cover. supporting naps mon their` upper edgeshingedly connected theretoiat il..`

The endwalls are. provided. with slits I8 ex.- tending diagonally outward and opening at the end edges of the endlwalls desirably in alignment with the, hingihgv scores l. This provides delectable portions i9 abovethe slits i8. The end walls have notch-like recesses 20 at their end edges and slits 2l extending diagonally inward providing de'ectabl'e portions 22. above the deflectableportions I9. i

The` corner naps have upwardly .projecting tongues 23 on their side edges `andI downwardly projecting deflectabletongues 2'4 spaced from the tongues Z3. TheV slits I 8 are adapted to receive the inner edges of the corner flaps when they are disposed in erected position on the outersides of-"the end* Walls. This permits the engagement of the-tongues 23A with theportions of the end walls above-the slits"I [-8` andi the engagement of the downwardly projectingtongues 24 with the end`-wa1l portions 2f2f orthey portions below the recesses.`

Thefi'ontwall' is provided with T'sha1;\ed's1its` The stem portions 2`6 of' these T-s-haped slits open to the top` edge ofthe front wall. When` the container isrerected with the tongues 23`` engaged with the edges of theslitsl I84 and1 the tongues 24 engaged over the bottom edges of the recesses, the parts arezveryfeffectiyely interlocled. However; when the cover supporting ilaps |.6 of the end` walls are? swung toi erected position they engage the i uppen edges of: thecorner naps and: further when the tongues |25 ane interloekedi` with the slits: 25 the:oovensupportingfiaps le are,` in ei'ect, held downwardly* into retaining engagement with the corner flaps., This: resultsin a structure which, even when mades of: relatively' light stock.,` is Very secure; and; relatively rigid and at the same time may bexquicklyopenediandireclosed; Y

-Tor openi the container it is necessary only to grasp the closureV flap' l0 between the tongues I2. thereofV andi pull: outwardly andiv upwardly. Thiswresults in retracting the-lugs t3' or drawing them towand each` otherand disengaging them fromr theirinterlocking engagement with the' slits afsiisv illustrated by dotteda lines inFig'. l andh also inrEigSi,
